I noticed that in the Instagram API when you get an image back, it looks something like this:
http://distilleryimage6.s3.amazonaws.com/a0efb5b418b711e391bd22000a1fbf1d_7.jpg
And by changing the _7 to say _5 or _6 you can get different sizes. But I have also noticed that some of the other sizes are NOT always available. Does anyone have info on what sizes are available or can you point me to a resource in the Instagram API that goes into more detail on image sizes supported via the API? Thanks.
The Instagram API should always return images in three sizes. All of which are square with side length of 150px, 306px and 612px. Videos are available at 480px square and 640px square resolutions.
